DIRIGIBLE HEAD-LAMP FOR VEHICLES.

Specification of Letters Patent. Patented Dec. 22, 1914,

Application filed April .1, 1914. Serial No. 828,844..

To all whom it may concern Be it known that I, Ennns'r GRAY, a citizen of'the United States, residing at Logan, in the county of Cache and State of Utah, have invented certain new and useful Improvements in Dirigible Head-Lamps for Vehicles, of which the following is a specification, reference being had to the accompanying drawings. This invention relatesv to head lamps for vehicles, and more particularly to that class of head lamps which are dirigible and are connected to. the steering mechanism of the vehicle so that upon turning of the steering wheels thereof, the lamps will be turned so that the driver of the vehicle is afforded a View of the road immediately in front of the vehicle when the same is making a turn or invention consists in the novel construction,

combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing's, in which, I

Figure 1 is a top plan view of my device,

showing the same connected to the frame of a vehicle; Fig. 2 1S a sectional view on theline 2-2 of 1; Fig. 3 is a detail perspective view showing the manner of connecting. one of the steering armsto one of the lamp posts; Fig. aisa section on the line 4-4= of Fig. 2; and Fig. 5 is a section on the line 55 of Fig. 1.

Referring more particularly to the drawings, the numeral 1 designates the forward ends of the bed rails of the chassis of a vehicle, 2 the front axle thereof, and '3 the knuckles which are connectedto the. opposite ends of the axle and which support the steering wheels 4 of the vehicle. Connected to 7 each bed rail adjacent its forward end, is

the bracket 5 in which a sleeve 6 is mounted, each of the sleeves being threaded interiorly ends.

and exteriorly at its opposite ends. The sleeves project above and below the brackets 5,-and nuts 7 are threaded on the opposite ends of-the sleeves to engage the upper and lower, faces of the brackets to maintain the sleeves in proper position therein. Threadably connected to the interior threads of 'each sleeve at its upper and lower ends are bearingball cups 8 and 9, respectively, in which aIser-ies of bearing balls 10 is mounted and rotatably disposed in each sleeve is the post 11 of a'ifamp bracket '12, each post carrying a cone 13' adjacent its upper end, for engagement with the bearing balls 10 in the upper bearing ball cups 8. The lower ends of the osts 11 project below the,

sleeves, and slidably disposed on the projecting end of each post is a cone 1 1 which is adapted to engage against the balls 10 disposed in the lower cup 9. To maintain the cones 14 in engagement with the balls 10 in the lower cups, a coil spring 15 is dis-- posed around each post, the upper e'nd of the spring engaging the cone 14, the lower end of the spring bearing against a pin 16 which is disposed through the projecting lower end of the 'post.

Connected to each of the knuckles'3 is a rearwardly extending steering arm- 17 which is offset upwardly at its rear end and is formed at the extremity of the upwardly extending portion with aball 18. A rod 19 is connected at its opposite ends to the upwardly extendingportion of each arm 17, so that upon operation of the steering mechanism of the automobile, the steering post, a suitable connecting rod 22 is provided which is oppositely threaded at its opposite Mounted on the outer threaded end of each arm 22 is a joint member 23, each of the joint members having a threaded recess 24 in one end for the reception of the outer threaded end of the rod 22 and each of the joint members .23 is provided with an upwardly projecting annular extension 25, through which and through the body of the .member' 23 is formed a vertical annular opening 26. The lower end of each opening 26 is adapted to receive a ball 18 upon-the steering arm 17, and the upper end of the opening 26 in each of the members 23 is y adapted to receive a nut 27 which closes the opening, and bearing against the under face 1 the members. The recesses 31 in the brace members 30 which receive theinner ends of the rods 22, are oppositely threaded from the recesses in the members 23, so that when p the oppositely threaded ends of the rods 22 are disposed in the recesses in the joint members by turning the rods 22, the position of the lamps supported upon the brackets 12 may be adjusted with relation to the I steering wheels. p Inthe practical use of my device, when the various parts are-connected in the man- ,ner heretofore described, it will be seen that when the'steering mechanism of the vehicle is'operated to turn the wheels, that the head v lamps will also be turned by'reason of the connection of the postsll with the steering argns 17 of the vehicle;

It will be readily seen that the vertical movement of the body of the vehicleis compensated for by reason of the springs 22 which i are disposed inthe path of the balls 18 and 2], carried by the-steering arms 17 and the arms 20, respectively, and it will also be readily seen that each of the lamps may be adjusted individually with relation to its adjacent steering wheel, upon rotation of the proper connecting rod 22,

Having thus fully described my invention, whatl desire to secure and claim by Letters- Patent, is

1,- lnj 'ecombination with the steering arm of a motor vehicle, of a lamp supporting post rotatably connected to the frame of the vehicle, a laterally extending operating arm connected at one end to the lower end of the F post, the free end of said operating arm being extended downwardly and provided with a head at its extremity, the free end of said steering arm being extended upwardly and provided with a head at its extremity, a connecting rod having enlarged ends, the enlarged ends of the connecting rod having vertically extending circular openings formed therein, the opening in one, of the enlarged ends being adapted to receive the head on the downturned end of the operating arm, the opening in the other enlarged end of the connecting. rod being adapted to receive the head on the upturned end of the steering arm, and a spring pressed cap mounted in each of the open ings for engagement against the head therein.

2. lhe combination with a vehicle frame, of a pair of brackets connected to the bed rails of,the frame adjacent their forward ends, a vertically disposed sleeve mounted and means for adjustably connecting eachof said arms to one of the steering arms of the vehicle, as and for the purpose described.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses. v ERNEST GRAY.
